Banner - Model QT50U Series -Chemical Resistant Ultrasonic Sensor

Senses extended range of up to 8 m. Features ultrasonic dead-zone of only 2.5% of the total range—75% less than comparable products. Available in analog or discrete dc models and in ac/dc universal voltage models with electromechanical relay output. Features a completely sealed, shock-resistant housing that is ideal for monitoring levels of liquids as well as solids. Uses a narrow sensing beam to detect targets at long range within confined areas—such as a storage tank—without interference from the tank walls. Available in chemically resistant models with a Teflon coating to protect the transducer. Compensates for temperature, for greatest sensing accuracy. Simplifies setup with push-button and remote TEACH-mode programming. Shows status during setup and operation, using highly visible LEDs indicators.
